I don't think so. By dragging the keyframe, you can put it where you want it to be (ie.

It doesn't make sense to > me. I haven't seen any kind of light cycles as you say. Is that what's shown in the compositor?

What is it? It allows to define the curve shape. You press "Ctrl", then, without releasing the key, you click and drag the small white square. Look at the shape of the curve: it changes. One "difficult" aspect is that while it's easy to move the input controle, you have to understand that the output control can only be accessed if the input control is already moved. Alex recently modified the Keyframe page. I don't know if he has finished yet so I won't edit that page for the moment.
